Published: December 02, 2019
Severity: Medium

OVERVIEW¶
A potential Reflected Cross-Site Scripting (XSS) vulnerability has been identified in the Management Console.
DESCRIPTION¶
This vulnerability is discovered when updating the message processor configuration from the source view in the Management Console.
IMPACT¶
By leveraging an XSS attack, an attacker can make the browser get redirected to a malicious website, make changes in the UI of the web page, retrieve information from the browser or harm otherwise. However, since all the session related sensitive cookies are set with httpOnly flag and protected, session hijacking or similar attacks would not be possible.
